Zadarma

What is Zadarma

Zadarma is an international telecommunications provider operating since 2006, offering cloud PBX, virtual phone numbers in 110+ countries, VoIP calling, SMS, and related business tools like CRM integration and AI voice agents. As of 2026-06-09, the company promotes a free tier for its cloud PBX and per-second billing for calls, with mobile apps available for Android and iOS. The service targets small businesses, call centers, and remote teams needing a virtual phone system without hardware investment.

How no-KYC is it?

Zadarma scores poorly on the no-KYC spectrum. The editorial assessment rates it at KYC Level 3, "Mandatory KYC for most features." While basic VoIP registration may be possible with just an email address, third-party evidence indicates that document verification is required for SMS activation and for obtaining most virtual number types. A 2026 review noted that "SMS activation took three days and two rounds of documentation," and Reddit users described the verification process as "endless and hopeless" with repeated failures. The KYC requirement appears to be a standard operational practice rather than an optional upgrade path, placing Zadarma firmly outside the no-KYC category for privacy-conscious users.

Privacy & security

Privacy protections are minimal. The service collects standard registration data and requires government-issued ID for feature activation. There is no evidence of Tor support, .onion access, or cryptocurrency payment options that would enhance anonymity. The platform emphasizes "international security standards" in marketing materials but does not detail specific logging policies for call metadata or SMS content. Users seeking anonymous virtual numbers should expect comprehensive identity linkage through the mandatory document verification workflow.

Payments, fees & limits

Zadarma operates on a fiat-only payment model. The FAQ explicitly lists credit card, PayPal, and bank transfer as top-up methods, no cryptocurrency options are mentioned. Pricing includes a free cloud PBX tier, regional calling plans for Europe, USA/Canada, and other zones, plus per-minute rates for virtual numbers and outgoing calls. The service offers test funds upon registration, but these cannot be accessed for SMS or number provisioning without completing KYC. There is no evidence of anonymous cash payment methods or privacy-preserving alternatives.

User experience & support

The platform provides extensive self-service resources including setup guides, API documentation, and an online chat support channel. The Android app holds a 3.2-star rating on Google Play based on approximately 4,100 reviews as of early 2026, suggesting mixed user satisfaction. Trustpilot shows 685 reviews for broader sentiment tracking. The registration process is currently marked "temporary unavailable" in multiple site crawls, indicating possible operational disruptions. Third-party reviews praise the speed of PBX setup but consistently criticize the verification bottleneck for core functionality.

Who it's for

Zadarma serves legitimate businesses needing affordable VoIP infrastructure with international reach. It is not appropriate for privacy-focused users, journalists, activists, or anyone requiring anonymous SMS verification. The service belongs in the NoKYC Directory primarily as a point of comparison, demonstrating how established telecom providers implement KYC as a default condition of service, and why alternatives with softer or no verification requirements exist for those who need them.
